Abstract

A television system comprises a first input terminal (20) for providing a composite video (CSCC) signal or a separated luminance (SCC) signal, and a second input terminal (15) for providing a separated chrominance (C) signal. A change-over switch (11) has a first input (a) coupled to the first input terminal (20) through a path including a color sub-carrier filter (9), a second input (b) coupled to the second input terminal (15) through a path not including the color sub-carrier filter (9), and an output (c) coupled to the input (d) of a color decoder (8). The change-over switch couples the input (d) of the color decoder (8) to the first input terminal (20) in a first position (a), and couples the input (d) of the color decoder (8) to the second input terminal (15) in a second position (b). A sub-carrier detector (CK) is coupled to the output (c) of the change-over switch (11) for detecting the presence or absence of a color sub-carrier. A control unit initially causes the change-over switch ( 11) to be in the first position (a) and thereafter causes said change-over switch (11) to remain in the first position (a) if a color sub-carrier is present at the output (c) of the change-over switch (11), but causes the change-over switch (11) to be in the second position (b) if a color sub-carrier is not present. Once the change-over switch (11) is in the second position (b), the control unit (1) causes said change-over switch (11) to be switched back to said first position (a) from said second position (b) if a color sub-carrier is still not present.

Description

【発明の詳細な説明】 ＦＢＡＳ信号またはＲＡＳ信号とＦ信号とに分離された信号を選択的に処理する ためのテレビジョン機器本発明は、請求項Ｉの上位概念によるテレビジョン機器 から出発する。[Detailed description of the invention] Selectively process signals separated into FBAS signal or RAS signal and F signal The invention relates to a television device according to the preamble of claim I. Depart from.

テレビジョン機器の５ＣＡＲＴコネクタには、ＦＢＡＳ信号に対するビデオ信号 発生器、例えばビデオレコーダ、カメラまたは符号発生器を接続することができ る。この種の発生器のＦＢＡＳ信号は現在のところ、５ＣＡＲＴコネクタのビン 番号２０に発生する。その他に、別個の出力側に一方ではＲＡＳ信号を、他方で は変調色搬送波Ｆを送出するビデオ信号発生器が存在する。５ｕｐｅｒ−ＶＨ３ （Ｓ−ＶＨ３）に適用されるこの信号伝送は、輝度信号と色搬送波との間にクロ ストークが発生せず、輝度信号の経路に色搬送波トラップフィルタを必要としな いという利点がある。この種の信号では、色搬送波のないＲＡＳ信号がビン２０ に供給され、変調された色搬送波が５ＣＡＲＴコネクタのビン１５に供給される 。The 5CART connector of the television equipment has a video signal for the FBAS signal. Can connect a generator, e.g. video recorder, camera or code generator Ru. The FBAS signal for this type of generator is currently available on the 5CART connector bin. Occurs at number 20. In addition, separate outputs can carry the RAS signal on the one hand and the RAS signal on the other hand. There is a video signal generator which delivers a modulated color carrier F. 5uper-VH3 This signal transmission applied to (S-VH3) requires a clock between the luminance signal and the chrominance carrier. No stalk occurs and no color carrier trap filter is required in the luminance signal path. It has the advantage of being In this type of signal, the RAS signal without color carrier is and the modulated color carrier is fed into bin 15 of the 5CART connector. .

前記２つの信号形式は機器において興なる処理を必要とする。従い、機器に手動 操作する切換スイッチを設けることが公知である。この切換スイッチにより例え ばＶＨ３と５−ＶＨ８との闇の相応の切換が可能で特表平４−５０６４４０　（ ２） ある、この切換は従い付加的操作を必要とする。その他、５−ＶＨ３信号が存在 している際に、カラーテレビジョン信号が存在しているのに、白／黒再生が行わ れる危険性がある。The two signal formats require extensive processing in the equipment. According to the equipment manually It is known to provide a changeover switch to be operated. For example, with this changeover switch If it is possible to switch between VH3 and 5-VH8, it is possible to switch between VH3 and 5-VH8. 2) Yes, this switching therefore requires additional operations. In addition, there is a 5-VH3 signal black/white playback occurs even though a color television signal is present. There is a risk of being exposed.

本発明の課題は、前記２つの信号の選択的処理用のテレビジョン機器を、２つの 信号形式を自動的に識別し、信号処理に対する相応の切換が行われるように構成 することである。An object of the present invention is to provide television equipment for selectively processing the two signals. Configured to automatically identify signal format and make corresponding changes to signal processing It is to be.

この課題は請求項１に記載された本発明により屏決される０本発明の有利な実施 形態は従属請求項に記載されている。This problem is solved by the invention as set forth in claim 1. Advantageous implementations of the invention Forms are set out in the dependent claims.

本発明では一義的に識別可能な基準の論理的評価により、２つの異なる信号での テスト過程が行われ、その結果として自動的にそれぞれの動作形式に適合した手 動接続が行われる。スイッチの手動操作はもはや必要ない、さらに機器がそれぞ れの信号に対して最適でない動作形式で作動すること、例えば、色画像内容を有 する信号が存在するのに５−ＶＨＳの際に白／黒再生が行われるということが排 除される０回路技術的コストは僅かである。というのは、はとんど既に存在して いる回路素子が使用されるからである。The present invention uses logical evaluation of uniquely distinguishable criteria to distinguish between two different signals. A test process is carried out as a result of which the procedure is automatically adapted to the respective operating type. A dynamic connection is made. Manual operation of switches is no longer necessary; operating in a mode of operation that is not optimal for the signal, e.g. It is excluded that black/white playback occurs during 5-VHS even though a signal exists. The eliminated circuit technical costs are low. Because most of them already exist. This is because the same circuit elements are used.

本発明は基本的に、前記の種々異なる信号が供給されるテレビジョン機器、例え ばテレビジョン受信機、モニタ、ビデオレコーダおよびその他のスタジオ回路に 適用することができる。本発明は、例えばＰＡＬ、ＮＴＳＣ，ＳＥＣＡＭ等のす べてのテレビジョン方式およびマルチスタンダードクロマデコーダ付の機器に適 用することができる。The invention basically relates to television equipment, e.g. For use in television receivers, monitors, video recorders and other studio circuits. Can be applied. The present invention applies to all PAL, NTSC, SECAM, etc. Suitable for all television systems and equipment with multi-standard chroma decoders. can be used.

本発明を以下、テレビジョン受信機の例に基づき説明する。このテレビシコン受 信機では５ＣＡＲＴコネクタに、ＶＨＳビデオレコーダからＦＢＡＳ信号または ５−ＶＨＳビデオレコーダからＢＡＳ信号とＦ信号に分離された信号を供給する ことができる。図１は本発明により構成されたテレビジョン受信機に対するブロ ック回路図、図２はテスト過程を説明するための線図である。The present invention will be explained below based on the example of a television receiver. This TV receiver The receiver connects the FBAS signal or FBAS signal from the VHS video recorder to the 5CART connector. 5-Supply separated signals into BAS signal and F signal from VHS video recorder be able to. FIG. 1 shows a block diagram for a television receiver configured according to the present invention. FIG. 2 is a diagram for explaining the test process.

５ＣＡＲＴコネクタ２には種々異なるテレビジョン信号をビデオ信号発生器から 印加することができる。5CART connector 2 accepts various television signals from a video signal generator. can be applied.

ＦＢＡＳ信号はコネクタ２のビン２０に印加される。The FBAS signal is applied to bin 20 of connector 2.

５−ＶＨＳビデオレコーダを接続する際にはＢＡＳ信号がビン２０に、変調色搬 送波Ｆがビン１５に印加される。５−ＶＨＳビデオレコーダは一方で信号ＢＡＳ を、他方で色搬送波Ｆまたは色信号を別個の線路に送出する。以下図１に示され た回路がビン２０またはビン２０と１５に印加されるこの異なる信号をどのよう に識別し、相応の切換を行うことができるのかを説明する。5-When connecting a VHS video recorder, the BAS signal is sent to bin 20, and the modulated color carrier is A transmit wave F is applied to bin 15. 5-VHS video recorder has signal BAS on the one hand and, on the other hand, the color carrier F or the color signal on separate lines. As shown in Figure 1 below How does this circuit handle this different signal applied to bin 20 or bins 20 and 15? It will be explained how it is possible to identify and make the corresponding switchover.

スイッチはニュートラル状態では開放しており、切換スイッチ１１は位置ａにあ る。ビン２０に色搬送波が印加されると、この色搬送波は帯域フィルタ９、切換 スイッチ１１および減衰素子１０を介してカラーデコーダ８の入力側に達する。The switch is open in the neutral state, and the changeover switch 11 is in position a. Ru. When a color carrier is applied to bin 20, this color carrier is passed through bandpass filter 9, switched It reaches the input side of the color decoder 8 via a switch 11 and a damping element 10.

このカラーデコーダ８では、カラーチャネルを自動的に遮断するため元々備わっ ている回路（カラーキラー）で色同期信号を評価することにより、出力側ｅに電 圧Ｕ１またはＵ２が形成される。この電圧は色同期信号が存在するか否か、すな わち変調色搬送波が存在するか否かを示す。カラーデコーダ８にて色搬送波の存 在することが検出されたなら、出力側ｅに電圧Ｕｌが発生する。この電圧はプロ セッサｌの入力側に供給される。ビン２０に色搬送波の存在が検出され、この色 搬送波はＦＢＡＳ信号の印加によってのみ発生し得るのであるから、２つのスイ ッチ４．１１はプロセッサｌにより切換電圧Ｕｌの線路１２を介して図示の状態 に保持される。従ってビン２０に発生するＦＢＡＳ信号は通常のように処理され る。輝度信号ＲＡＳはカラートラップフィルタ３と遅延段５を介してビデオプロ セッサ６に達する。色搬送波Ｆは、帯域フィルタ９、スイッチ１１、減衰素子１ ０を介してカラーデコーダ８の入力側ｄに達する。This color decoder 8 is originally equipped to automatically cut off color channels. By evaluating the color synchronization signal with a circuit (color killer), a voltage is applied to the output side e. A pressure U1 or U2 is created. This voltage depends on whether the color sync signal is present or not, i.e. That is, it indicates whether a modulated color carrier exists or not. Color decoder 8 detects the presence of color carrier waves. If its presence is detected, a voltage Ul is generated at the output e. This voltage is professional is supplied to the input side of processor l. The presence of a color carrier in bin 20 is detected and this color Since the carrier wave can only be generated by applying the FBAS signal, two switches are required. switch 4.11 is activated by processor l via line 12 of switching voltage Ul to the state shown. is maintained. Therefore, the FBAS signal occurring in bin 20 is processed as usual. Ru. The luminance signal RAS is sent to the video processor via a color trap filter 3 and a delay stage 5. Reach Sessa 6. The color carrier wave F is passed through a bandpass filter 9, a switch 11, and an attenuation element 1. 0 to the input d of the color decoder 8.

カラーデコーダはその出力側ｆ、ｇに色差信号Ｕ、■を形成する。プロセッサ６ は受像管７に対して３つの色信号Ｒ，Ｇ、Ｂを形成する。The color decoder forms color difference signals U, 2 at its outputs f, g. processor 6 forms three color signals R, G, and B for the picture tube 7.

スイッチ４と１１が図示の位置にある際、カラーデコーダ８に色同期信号、従い 色搬送波が検出されなければ、不確実な状態が生じる。すなわち、ビン２０に色 搬送波なしの白／黒信号が印加されているか、または５−ＶＨ３信号である可能 性がある。５−ＶＩ（Ｓ信号では色搬送波ＦがＲＡＳ信号から分離されてビン１ ５に印加されるからである。そのときは色搬送波の存在を示す電圧Ｕ２が形成さ れる。プロセッサｌはこれにより切換電圧Ｕｓ２を形成し、この電圧Ｕｓ２によ り線路１２を介して切換スイッチｌｌが位置すに制御される。それによりビン１ ５はカラーデコーダ８の入力側ｄに接続される。カラーデコーダ８は新たに、色 搬送波が存在するか否かを検出する。色搬送波の存在が検出されたならば、これ はビン１５に色搬送波が印加されていることを意味する。次にプロセッサは切換 電圧Ｕｓ２を送出し、ビン１５の色搬送波を評価するために、切換スイッチ１１ を位置すに保持する。同時にＵｓ２によりスイッチ４が閉成され、それにより色 搬送波トラップフィルタ３が橋絡される。これを行うのは、ＲＡＳ信号ではビン ２０に色搬送波Ｆがもはや存在せず、従い色搬送波トラップフィルタ３により相 応の周波数領域を抑圧することは不利にしかならないからである。When switches 4 and 11 are in the positions shown, the color decoder 8 receives a color synchronization signal, If the color carrier is not detected, an uncertain condition occurs. That is, the color in bin 20 White/black signal without carrier is applied or can be 5-VH3 signal There is sex. 5-VI (In the S signal, the color carrier F is separated from the RAS signal and This is because it is applied to 5. A voltage U2 is then formed indicating the presence of a color carrier. It will be done. Processor l thereby forms a switching voltage Us2 and uses this voltage Us2 to A changeover switch 11 is controlled to be in position via a transmission line 12. Therefore, Bin 1 5 is connected to the input side d of the color decoder 8. Color decoder 8 newly supports color Detect whether a carrier wave is present. Once the presence of a color carrier is detected, this means that a color carrier wave is applied to bin 15. Then the processor switches In order to send out the voltage Us2 and evaluate the color carrier of the bin 15, the changeover switch 11 is activated. hold in position. At the same time, switch 4 is closed by Us2, which causes the color The carrier trap filter 3 is bridged. This is done by using bins in the RAS signal. 20, the color carrier F is no longer present, and therefore the color carrier trap filter 3 This is because suppressing the corresponding frequency range is only disadvantageous.

しかし切換スイッチ１１の位置すでカラーデコーダ８に色搬送波が検出されなけ れば、これはビン１５に色同期信号も色搬送波も存在していない、すなわち５− ＶＨ３が印加されていないことを意味する。ここでは、５−ＶＨＳ信号は白／黒 画像の場合も常に色同期信号を含むことが前提とされる。テストフェーズの開始 時、ビン２０の信号に色搬送波が検出されなかったので、この場合はビン２０は 色搬送波ＦなしのＲＡＳ信号である。すなわち白／黒信号が取り扱われる。従っ て、プロセッサｌは再び切換電圧Ｕｓｌを形成し、この電圧Ｕｓｌにより切換ス イッチ１１は再びニュートラル位置ａへ復帰切替される。スイッチ４はこの場合 、閉成されたままで構わない、というのはビン２０のＲＡＳ信号は白／黒信号で あり、色搬送波を含まないからである。However, the color carrier wave must be detected by the color decoder 8 at the position of the changeover switch 11. , this means that there is no color sync signal or color carrier in bin 15, i.e. 5- This means that VH3 is not applied. Here, the 5-VHS signal is white/black It is assumed that images always include a color synchronization signal. Start of testing phase In this case, bin 20 is This is a RAS signal without color carrier F. That is, white/black signals are handled. follow Then, the processor l again forms the switching voltage Usl and uses this voltage Usl to activate the switching voltage Usl. The switch 11 is switched back to the neutral position a. In this case switch 4 , it doesn't matter if it remains closed, because the RAS signal of bin 20 is a white/black signal. This is because it does not include a color carrier wave.

本発明の回路は常に、自動的に次の３つの動作可能状態に適合する。The circuit of the present invention always automatically adapts to the following three operational states:

１、カラー内容を含むＦＢＡＳ信号がビン２０に印加される状態。1. A condition in which an FBAS signal containing color content is applied to bin 20.

２．８ＡＳ信号がビン２０に、色搬送波Ｆがビン１５に印加される状態。例えば ５−ＶＨＳレコーダより、３、色搬送波のないＦＢＡＳ信号がビン２０に印加さ れる状態。すなわち純粋な白／黒信号。2.8AS signal is applied to bin 20 and color carrier F is applied to bin 15. for example 5-From the VHS recorder, 3. An FBAS signal without color carrier is applied to bin 20. state of being In other words, pure white/black signal.

切換スイッチ１１の出力側Ｃとカラーデコーダ８の入力側ｄとの間の減衰素子１ ０は次の目的を有する。Attenuation element 1 between the output side C of the changeover switch 11 and the input side d of the color decoder 8 0 has the following purpose:

ビン２０の信号は常に不可避の搬送波残雪成分を色搬送波の周波数領域に有し、 従いこの残留成分がカラーデコーダ８の入力側ｄに達し、解像度のエラーを惹起 し得る。従って、図２のテスト過程中は入力側ｄに供給される信号を約１０ｄＢ 減衰するのが有利である。The signal in bin 20 always has an unavoidable carrier residual snow component in the color carrier frequency domain; Therefore, this residual component reaches the input side d of the color decoder 8 and causes a resolution error. It is possible. Therefore, during the test process of Fig. 2, the signal applied to the input side d is It is advantageous to attenuate.

そのため、図２のテスト過程中はそれぞれ、プロセッサＩにより線路１３を介し て、１０ｄＢの減衰度の減衰素子ＩＯが投入接続される。上に述べた３つの動作 形式のうちのそれぞれのニュートラル動作中は、減衰素子１０は遮断される。Therefore, during the test process of FIG. Then, an attenuation element IO with an attenuation degree of 10 dB is connected. The three actions mentioned above During neutral operation of each of the types, the damping element 10 is cut off.

図２のテスト過程Ｔで検出された、３つの状態の１つをプロセッサｌに記憶する と有利である。このようにすると、例えば受信機の遮断および再投入接続後に調 整すべき状態が既知であるから、検出する必要がない、新たなテスト過程は、Ａ Ｖキーが新たに操作されるか、または５ＣＡＲＴコネクタ２のビン８に新たな再 生過程が週報された場合に行う。One of the three states detected in the test process T of FIG. 2 is stored in the processor l. It is advantageous. In this way, for example, after disconnecting and reconnecting the receiver, A new test process that does not need to be detected because the state to be corrected is known. If the V key is operated anew or a new This is done when the raw process is reported weekly.
